Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33616820, here are decompositions:

19 + 33616801 = 33616820
67 + 33616753 = 33616820
109 + 33616711 = 33616820
271 + 33616549 = 33616820
313 + 33616507 = 33616820
373 + 33616447 = 33616820
421 + 33616399 = 33616820
439 + 33616381 = 33616820

Showing the first eight; more decompositions exist.
